Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33485020, here are decompositions:

53 + 33484967 = 33485020
113 + 33484907 = 33485020
167 + 33484853 = 33485020
227 + 33484793 = 33485020
251 + 33484769 = 33485020
269 + 33484751 = 33485020
311 + 33484709 = 33485020
347 + 33484673 = 33485020

Showing the first eight; more decompositions exist.
